A handheld cable stripping tool

Abstract

The present invention relates to a handheld cable stripping tool, comprising a handle, a knife seat and a support for placing a cable, wherein a blade is installed in the knife seat, and the support is fixed at the front end of the handle. The knife seat is hinged at the middle part of the handle and the tip of the blade corresponds to the support to strip the cable. A pulley is used as a track for the cable, and the pulley rolls during longitudinal cutting of the cable to reduce friction. During ring stripping, the cable can be fixed in a V-shaped groove to keep the cable stable and prevent the cable from slipping out during stripping. The depth of the knife tip cutting into the cable is fine-tuned by adjusting the bolt transmission to control the stripping depth. The tool is easy to carry and can be operated by one person to achieve stripping, which is very convenient for construction personnel to work at high altitude or alone, saving manpower and equipment costs and improving work efficiency.

Description

Technical Field

[0001] The invention relates to a handheld cable stripping tool. Background Art

[0002] Many power facilities such as substations need to be stripped of a large number of cables during construction. Due to the small space in the substation, the existing wire stripping equipment cannot be placed at the work site. At present, power installers directly use utility knives to strip the wires, without any protective measures. They only rely on manpower to fix the cables and rely on personal experience to cut into the cables to a certain depth. The problems are: the cables may be offset when using utility knives, causing the risk of hand injury, and there is no portable and safe wire stripping tool; when cutting into the cable, it depends on personal experience. If it is too deep, it is easy to damage the cable core wire, and if it is too shallow, it is easy to make the cable skin unable to be stripped, and it needs to be cut again. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a handheld cable stripping tool that can be carried and used, has a controllable cutting depth and can be applied to cables of different models. The technical solution adopted by the present invention is as follows:

[0004] A handheld cable stripping tool comprises a handle, a knife seat and a support for placing a cable, wherein a blade is installed in the knife seat, the support is fixed at the front end of the handle, the knife seat is hinged at the middle part of the handle and the tip of the blade corresponds to the support for stripping the cable.

[0005] The support of the handheld cable stripping tool comprises a front pulley, a rear pulley and two left and right side plates. The front pulley and the rear pulley are arranged front and back and are rotatably installed between the side plates to support the cable to achieve longitudinal cutting.

[0006] The handheld cable stripping tool has a V-shaped groove on the side plate corresponding to the tip of the knife blade for clamping the wire to achieve ring stripping.

[0007] The handheld cable stripping tool has an upper tail end of the handle provided with an adjusting bolt with adjustable threads, and the lower end of the adjusting bolt presses the tail end of the knife seat to control the cutting depth of the blade tip.

[0008] The handle and the support are arranged at an angle between the handle and the plane where the support is located, and the angle is 20° to 35°.

[0009] The above-mentioned handheld cable stripping tool has a baffle on the upper part of the handle for blocking the knife seat in the length direction, and an upwardly inclined limit plate is provided at the front end of the baffle. The limit plate and the baffle jointly limit the rotation angle of the knife seat to an angle of -10°~20° with the straight line where the cable is located.

[0010] The above-mentioned handheld cable stripping tool has a limit pin threadedly connected to the support for limiting the downward movement of the handle.

[0011] In the above-mentioned handheld cable stripping tool, the center distance between the front pulley and the rear pulley is 60-70 mm; the length of the knife seat is 120-150 mm.

[0012] The front pulley and the rear pulley of the handheld cable stripping tool are both V-shaped wheels, the two side plates are connected by a threaded connecting rod, and the right end of the connecting rod is threadedly connected to the front end of the support.

[0013] The beneficial effects of the present invention are as follows: the pulley is used as the track of the cable, and the pulley rolls when the cable is longitudinally cut, thereby reducing friction. The cable can be fixed in the V-shaped groove during ring stripping to keep the cable stable and prevent the cable from slipping out during stripping. The depth of the cutter tip cutting into the cable is fine-tuned by adjusting the bolt transmission to control the stripping depth. The tool is easy to carry and can be operated by one person to achieve stripping, which is very convenient for construction personnel to work at high altitude or alone, saving manpower and equipment costs and improving work efficiency.
